Physical properties of Acids
Acids have the following properties:
Acids have a sour tasteAcid solutions have pH values less than 7. (More about pH values in the next few sub-topics)Acid solutions turn blue litmus paper (an indicator) red.
All acids have a sour taste in dilute solution.
The sour taste found in lemon juice is due to citric acid.Vinegar is sour because it contains ethanoic acid.Sour milk contains lactic acid.
Chemical Properties of Acids
There are three common reactions of acids:
$\text{Acid} + \text{metal} \rightarrow \text{salt} + \text{hydrogen gas}$$\text{Acid} + \text{base} \rightarrow \text{salt} + \text{water}$$\text{Acid} + \text{carbonate} \rightarrow \text{salt} + \text{water} + \text{carbon dioxide gas}$
